Noise absorbers with structured surface
Napped or egg crate foams as well as pyramid-profiled foams are the best known acoustic foam materials and rightly considered as very good sound absorbers. Their structured surface ensures excellent absorption values across all frequency bands.
soni WAVE is a noise-control product made from a structured PUR-ester foam. In contrast to standard napped foam materials, it has an air-permeable, sealed surface (special Cello® process) that provides dirt resistance and makes soni WAVE oil-, water- and fuel-repellent. Thanks to its robust structure and excellent noise absorption capability, the egg box foam soni WAVE is especially suited for technical applications.
soni PYRAMIDE is an outstanding sound absorber made from a soft open-cell melamine resin foam (Basotect ®). With their surface sculpted in a pyramid pattern, soni PYRAMIDE panels score with especially high noise absorption capability and excellent fire safety properties (flame retardant as proven by the B1 test according to DIN 4102.) Its visually attractive surface and low weight add to the advantages of soni PYRAMIDE as a decorative and effective pyramid acoustic foam that shortens the reverberation time and substantially improves the acoustic conditions in indoor spaces.
soni PYRAMIDE panels are available in white and light gray.
